A Modified Wave-number Domain Algorithm for Missile-borne Squinted SAR Data Processing

abstract Arrays of detectors placed at discrete points are often used in problems requiring high resolution in wave number for a limited number of detectors. The resolution performance of an array depends on the positions of detectors as well as the data processing of the array output. The performance can be expressed in terms of the “spectrum window”. Spectrum windows may be designed by a general least-square fit procedure. An alternate approach is to design the array to obtain the largest uniformly spaced coarray, the set of points which includes all the difference spacings of the array. Some designs obtained from the two methods are given and compared.

The actual airborne dual-channel data is disposed to indicate the moving target by ATI. In order to solve the problems caused by the unideal movement in the flight and other engineering factors which influence the GMTI, the paper presents the method to compensate the interference phase base on calculate the phase centroid of every sub-image. Besides, this paper simplifies some data processing to realize the real-time GMTI and improves the efficiency. With this method, the actual SAR data is proceeded to get the targets position and movement parameter. Results prove the validity of the approach.
